Hep-Ex explores the fascinating intersection where particle physics meets experimental reality. This field investigates how scientists build massive detectors and accelerate particles to test the fundamental laws of nature, turning abstract theories into measurable data. It is the rigorous process of searching for new particles or forces that could reshape our understanding of the universe, often requiring years of collaboration and engineering.
At Gist.Science, we ensure these discoveries become accessible to everyone. We process every new preprint in this category directly from arXiv, generating both plain-language explanations for curious readers and detailed technical summaries for specialists. Our goal is to bridge the gap between complex experimental results and public understanding without losing scientific nuance.
Below are the latest papers in Hep-Ex, freshly summarized and ready for you to explore.
Using a single-charge sensitive SuperCDMS-HVeV detector operated underground at Fermilab with minimized background luminescence, this study presents new constraints on low-mass dark matter electron scattering and absorption interactions, achieving sensitivity down to 1 MeV/c² for scattering and probing axionlike particles and dark photons with masses greater than 1.2 eV/c².
This paper calculates the tensor-polarized twist-3 parton distribution function for the spin-1 deuteron by applying twist-2 relations to the known twist-2 function , demonstrating that is comparable in magnitude to and suggesting that current and future facilities like JLab and the EIC are well-suited to investigate these higher-twist effects.
This paper presents an enhanced version of the TrackFormers framework for High-Energy Physics track reconstruction, introducing custom Transformer attention mechanisms, a novel geometric projection with lightweight clustering, and joint model conditioning to improve both accuracy and efficiency for upcoming High-Luminosity LHC data challenges.
Using continuum Schwinger function methods, this paper demonstrates that the pion and kaon possess significant intrinsic orbital angular momentum in their rest frames and light-front projections, revealing them as complex bound states with observer-dependent OAM compositions that must be accounted for in hadronic observables.
This paper systematically analyzes Bell nonlocality and entanglement in decays into baryon-antibaryon pairs produced at BESIII, revealing a distinct hierarchy where exhibits maximal quantum correlations, shows angle-dependent violations, and remains in a separable state, thereby establishing this system as a promising platform for testing quantum foundations in high-energy physics.
This paper reviews the latest experimental results from the 18th Workshop on Top-Quark Physics, highlighting how the field has evolved over thirty years from initial discovery to a mature era characterized by precision measurements, new scattering processes, and the detection of subtle effects through refined techniques.
This paper investigates the thermodynamic geometry of the hadron resonance gas model with and without excluded volume effects across real and imaginary baryon chemical potentials, utilizing the scalar curvature to map phase structures, determine a baryon gas limitation temperature that aligns with lattice QCD predictions, and derive a simple sufficient condition for quark deconfinement.
This paper outlines the development, production procedures, and advantages of Belle II's run-dependent Monte Carlo simulations, which utilize time-dependent detector conditions and beam backgrounds to achieve higher granularity and accuracy compared to traditional run-independent methods.
Using data from the Dark Matter Particle Explorer, this study analyzes eight electron Forbush decreases between 2016 and 2024 to reveal diverse energy-dependent recovery behaviors that are linked to the geometric properties of coronal mass ejection disturbances in interplanetary space.
This paper summarizes the main features, Run-3 performance, and physics impact of the upgraded ATLAS Trigger system, which was enhanced to handle increased luminosity and pile-up conditions while reducing the event rate for offline analysis.
